Corpus Christi Site Plan Requirements: Complete Guide for Building Permits
Creating a site plan for a building permit in Corpus Christi, Texas requires meeting specific requirements set by the Development Services Department. Corpus Christi's development is governed by the Unified Development Code (UDC), with critical considerations for coastal construction, hurricane wind loads, flood zone compliance along the Gulf Coast, Island development (North Padre Island and Mustang Island), and the Texas Windstorm Insurance Association (TWIA) certification requirements.
What Is a Site Plan and Why Does Corpus Christi Require One?
A site plan is a scaled drawing showing your property boundaries, existing structures, proposed construction, setbacks, and site features. Development Services requires a site plan for all building permit applications to verify compliance with the UDC and the International Building Code as adopted locally. Use the city's GIS portal at cctexas.com/gis to look up zoning and flood zone data.
